Wait a second: isn't that exactly what 'git reset --hard' is for?
I doubt[*] 'git reset --merge' could be anything but a mistake when used
outside the context of a merge (remember that the plumbing is called
"read-tree", not "reset").
[*] This is disingenuous of me. I used to use "git reset --merge <commit>"
with the intent of "git reset --keep <commit>", since the latter did
not exist yet. But I was wrong. :)
Here's a start for the interested:
